The vertical tab rail (tabOrientation 'vertical') listed names and nothing
else, while the rich sidebar and both home screens already answered the
question a docked column exists to answer: which of these sessions wants me
next, and how long has it been like that. The rail is a docked column too, so
it now draws the same row.
- New per-device setting tabRailDetail ('rich' | 'simple', default rich),
App Settings -> Appearance -> Tabs, in SettingsUpdateSchema + displayKeys and
stamped as data-tab-rail-detail by the pre-paint script, so a detailed rail
does not flash through simple rows on every load.
- ONE gate for both vertical surfaces: isRichTabRows() =
isSessionSidebarRich() || isTabRailRich(). The row model, the markup and the
20s in-place clock are the existing rich-sidebar ones, classified by
_mobileOverviewState/_mobileOverviewSince, so the rail, the sidebar, the
desktop home rail and the phone overview cannot disagree about what
"working" means or which stamp measures it.
- Detail rides on its OWN attribute, exactly as the sidebar's does, so every
existing [data-tab-orientation='vertical'] rule keeps matching both variants
untouched. A flip of detail ALONE still forces a full render (the stamps line
is emitted by the row template, not toggled by CSS) and re-runs
applyTabWrapSettings(), which owns the folder line and is now rail-aware.
- CSS: every rich paint rule gains a rail twin as a COMMA-GROUPED selector,
never :is() - an :is() list takes its most specific argument, which would
lift the sidebar arm from (0,3,1) to the rail's (0,5,1) and let these rules
outrank things they never used to.
- Width is why there are thresholds. At 256px the stamps line ellipsizes
mid-word, the same reason the rich sidebar is 300px, so a rail that has never
been sized defaults to 320 (RICH_DEFAULT_WIDTH, the existing Wide preset,
which also keeps the settings select on a named choice). A width the user has
chosen is never overridden: below 288px the created stamp is dropped rather
than truncated (tab-rail-tight, CSS only) and below 240px the rows go back to
simple (tab-rail-compact, which re-renders).
- The rich clock is armed and disarmed by applyTabOrientation() as well as
applySessionListLayout(); a leaked interval would rewrite stamps in a list
that no longer has any.
Also fixes a data-loss bug in the inline tab rename that predates the rail and
reproduces in every layout, header strip included: Escape set the input to ''
and blurred it, and the blur handler commits - so cancelling a rename PUT an
empty name, and the tab fell back to its folder label (measured against a live
server: ["rail-alpha","","rail-gamma"]). Escape now calls cancelRename(), which
invalidates the edit so the blur that follows the input's removal is a no-op.
Tests: rail-detail gate, the three ways it turns back off (simple, compact,
horizontal), sidebar-wins, render-on-detail-flip and the plumbing/CSS guards in
test/session-list-layout.test.ts; the rename cancel in test/inline-rename.test.ts
(browser suite), pinned by running it against the old code first. Verified live
against a real server on an isolated instance: detailed/simple/compact/header/
sidebar variants, click-select, the ... menu, inline rename, Alt+N, the in-place
stamp tick and a full settings-picker round-trip including reload.
